One of the clinical signs and symptoms of fluctuating hearing loss Meniere’s disease. Meniere’s disease, also known as Meniere’s syndrome, is a sudden onset non-inflammatory labyrinthine lesion with clinical manifestations such as vertigo, deafness, tinnitus and sometimes a feeling of stuffiness in the affected ear. Excessive fatigue and lack of sleep are among the predisposing factors for Ménière’s disease. Therefore, patients with Ménière’s disease should pay attention to rest and ensure sufficient sleep, whether during or after an attack. At the same time, we should try to avoid turning the head and neck back and forth, for example, inner ear lesions may affect the vestibular system and cause vertigo attacks due to the change of head position. 1. Vertigo is mostly sudden rotational vertigo. When you open your eyes, you feel that the objects around you are rotating in a certain direction and plane, or that you are swaying from side to side. When the eyes are closed, the above symptoms are reduced. Therefore, the patient often adopts a certain position to lie still with eyes closed during the attack, not daring to turn. Although the patient sometimes falls to the ground due to shock, he or she is completely conscious. Patients often experience nausea and vomiting, pallor, cold sweats, and a drop in blood pressure. It resolves spontaneously after a few minutes or hours. The symptoms disappear and the patient goes into an intermittent period. The length of the intermittent period varies from person to person, and there are those who have only one attack in their lifetime, and those who have repeatedly had multiple attacks. Tinnitus is a low-pitched blowing tinnitus in the affected ear at first, but it becomes a high-pitched persistent tinnitus after a long time. During the attack of vertigo, the tinnitus increases suddenly, and then decreases or disappears naturally during the interval. 3. Deafness In the early stage, the deafness is not conscious, but becomes obvious after many attacks of vertigo. It is usually unilateral. Occasionally, it is bilateral. Deafness is aggravated during vertigo attacks and improves in the interval, with fluctuating hearing damage, or without fluctuation in severe cases. The general tendency of hearing impairment often deteriorates with the number of attacks. 4. Head fullness During vertigo attacks, some patients have a feeling of fullness, heaviness, pressure, or burning around the ear on the affected side of the head or in the ear. 5. Nystagmus When observing the patient’s eyes at the climax of the attack, you can usually see involuntary fluttering in fast and slow phases.
